Abstract

A transmitting unit of a portable telephone apparatus transmits radio signals by using at least two antennas and simultaneously energizing those antennas by use of a predetermined amplitude ratio and a predetermined phase difference so that the direction of the main beam of a radiation pattern is substantially opposite to that of the audio radiation of a speaker, and so that the average effective gain is larger than that of when a single antenna is energized. The above energization of at least two antennas is performed only for transmission of telephone call. A receiving unit of the portable telephone apparatus receives radio signals by using at least two antennas, and selectively receives, by the diversity reception method, the radio signal having the highest level of those radio signals received by those antennas.
